Erbium-Doped Fiber

Erbium-Doped Fiber is a special gain fiber for fiber amplification and laser applications in the 1.5 μm band. The product adopts an erbium-doped core design, with an operating wavelength covering 1530–1565 nm. It has high core absorption capability and good optical performance, and can achieve stable optical signal gain under pump light. Its core numerical aperture is 0.22 ± 0.02, mode field diameter is 5.7 ± 0.8 μm, and the core absorption coefficient at 1530 nm reaches 20.0 ± 3.0 dB/m. The product has good geometric consistency and mechanical reliability, and is suitable for applications such as fiber amplifiers, fiber lasers, ASE light sources, fiber sensing, and scientific research experiments. Customized services can be provided according to actual requirements.
